Have you used infrastructure as code tools before? Which ones?

Sample answer to the question

Yes, I have experience with infrastructure as code tools. I have used Terraform and CloudFormation for managing infrastructure resources on public cloud platforms like AWS and Azure. In my previous role, I was responsible for automating the deployment of virtual machines, networking configurations, and storage resources using Terraform. I also used CloudFormation to create and manage infrastructure stacks as code. These tools allowed me to define and provision infrastructure resources in a repeatable and scalable manner. I found them to be efficient in managing complex cloud infrastructure and ensuring consistency across environments.

A more solid answer

Yes, I have extensive experience with infrastructure as code tools. I have worked with both Terraform and CloudFormation extensively to manage infrastructure resources on various cloud platforms including AWS, Azure, and Google Cloud Platform. In my previous role, I was responsible for provisioning and configuring virtual machines, networking components, load balancers, and database services using Terraform. I also utilized CloudFormation to define and deploy infrastructure stacks as code. These tools allowed me to define the desired state of my infrastructure and provision resources in an automated and repeatable manner. I found them to be highly efficient in terms of managing complex and dynamic cloud infrastructure, ensuring consistency, and enabling rapid deployment and scaling.
